I am wondering if it's because of the long cage derailleur?
birdie is a tad flawed in design.
solutions i know of are fit narrow tyres, change to ihg .
else change to a short cage rear mech which also improves ground clearence. then the cage doesnt reach down to the tyre. if you do this you may want to fit a chain tensior,else chain falls off in folding, 70 pounds please. but then you can get rid of the chain catcher that gets stuck inthe rear cogs and breaks transmission parts as it locks up. it worth shelling out on the new chain tensior in the long run.
